COMPARATIVE METHODOLOGIES FOR ESTIMATING ON-WATER RESPONSE COSTS FOR MARINE OIL SPILLS

ABSTRACT This study reviews three alternative oil spill response cost estimation methodologies as applied to hypothetical spill scenarios in the Gulf of Mexico and San Francisco Bay, California: (1) a model derived from historical data on various spill factors that drive overall cleanup costs; (2) a method using U.S. Area Contingency Plan (ACP) spill scenario plans to estimate costs for mechanical containment and recovery costs to be extrapolated to other hypothetical spill scenarios; and (3) a method that estimates the labor and equipment required for mechanical containment and recovery operations and the resulting costs. A method for estimating dispersant costs is also discussed. The easy-to-use model derived from historical data is shown to be a good cost estimation tool.
